As Walter went down, he made a clutch at the man's watch-chain, or rather the chain which belonged among the Russell heirlooms. He caught the top guard and the chain parted, one half remaining in the boy's hand, and the other fast to the timepiece.
"Help me catch him!'" gasped the youth, as soon as he could get up. His breast had struck the edge of one of the steps, and he was momentarily winded.
"I will," answered the man who lived in the tenement. "Stop there!" he called out, and set off in pursuit, with Walter beside him. But the Irishman was old and rheumatic, and soon felt compelled to give up the chase. "I can't match ye!" he puffed, and sank down on a step to rest; and once again Walter continued the chase alone.
Had the thief, Deck Mumpers, been perfectly sober, he might have escaped with ease, for he was a good runner, and at this hour of the evening hiding-places in such a city as Boston, with its many crooked thoroughfares, were numerous. But the liquor he had imbibed had made him hazy in his mind, and he ran on and on, with hardly any object in view excepting to put distance between himself and his pursuer.
He was heading eastward, and presently reached a wharf facing the harbor and not a great distance from the Congress Street bridge. Here there was a high board fence and a slatted gate, which for some reason stood partly open. Without a second thought, he slipped through the gateway, slid the gate shut, and snapped the hanging padlock into place.
"Now he'll have a job following me," he chuckled. "I wonder what sort of a place I've struck?" And he continued on his way, among huge piles of merchandise covered with tarpaulins.
Walter had come up at his best speed and was less than a hundred feet away when the gate was closed and locked.
"You rascal!" he shouted, but Deck Mumpers paid no attention to his words. "Now what's to do?" the boy asked himself, dismally.
He came up to the gate and examined it. It was all of nine feet high, and the palings were pointed at the top. Could he scale such a barrier?
"I must do it!" he muttered, and thrust one hand through to a cross brace. He ascended with difficulty, and once slipped and ran a splinter into his wrist. But undaunted he kept on until the top was gained, then dropped to the planking of the wharf beyond.
